Pull Live Crypto Market Data Without a Rate Limited Key

Crypto dashboards, alerts and portfolio trackers all need the same boring thing first: a clean list of coins with price, market cap, volume and recent change. The usual path is signing up for a data plan and babysitting an API key. You often do not need to. CoinGecko serves a public market endpoint that returns a tidy array of coins: GET https://api.coingecko.com/api/v3/coins/markets ?vs_currency=usd&order=market_cap_desc&per_page=250&page=1 &price_change_percentage=1h,24h,7d,30d No key

Automating Dev.to Cross-Posts with n8n: From Manual to Hands-Free in 10 Minutes

I finally got tired of manually copy-pasting my blog posts over to Dev.to. It’s one of those chores that either gets forgotten or ends up with broken formatting and missing canonical links, so I decided to automate the whole thing. The article walks through building a self-hosted automation pipeline using n8n that pulls content from a personal portfolio and syndicates it perfectly every time. Configures a 5-minute polling interval via a Schedule Trigger to check for new content. Uses a Function

philliant on youtube is the companion to the writing

thesis philliant.com is still the main home for my writing. the channel is philliant on youtube, and it is going to be the companion space where i talk through the posts, explain the chapters, and add the kind of spoken context that does not always fit cleanly on the page. most of what i publish starts here on the site. the shorter posts live in the posts section, and they cover the mix of ideas i keep coming back to, including technology, data engineering, ai workflows, productivity, and the

reCAPTCHA v2 vs v3 vs Enterprise — how to tell which one you're fighting (and how to solve each)

reCAPTCHA v2 vs v3 vs Enterprise — how to tell which one you're fighting "reCAPTCHA is blocking me" is the start of a debugging session, not the end of one. There are four practical variants — v2 checkbox, v2 invisible, v3 score, and Enterprise — and they behave completely differently. They fail differently, they're solved differently, and the call you make to a solver isn't the same shape. So before you touch any code, the first job is identifying which one you're up against. The page tells y

How I Built and Secured a Self-Hosted Stack

I built and operate a 13-service self-hosted platform on a single Linux VPS: a personal AI chat interface, budgeting, RSS, notes, bookmarks, uptime monitoring, a dashboard, dev utilities — and a self-hosted autonomous AI agent. Everything sits behind one reverse proxy with automatic HTTPS, most of it behind single sign-on, and the whole thing is captured as Docker Compose config that survives reboots and rebuilds. Up front, honestly: this is a personal, self-directed project, and I'd put my leve

Building a Binary MLM System: From Tree Algorithms to Transactional Ledgers

Ever had to build a system where every single user action triggers a recursive recalculation across a massive, branching tree? I recently went down the rabbit hole of Multi-Level Marketing (MLM) architecture, and it is a lot more complex than just drawing circles on a whiteboard. The article walks through the heavy lifting required to build a binary commission engine from scratch, focusing on the intersection of tree data structures and high-integrity financial ledgers. Implementation of the Bin

How to Screen Thousands of Stocks Without a Data Provider

Stock screeners feel like something you should have to pay a data vendor for. Market cap, sector, P/E, dividend yield, RSI, daily change, all of it across thousands of tickers, updated through the day. In practice a lot of that is one keyless JSON call away, and you can run it yourself. TradingView's screener page is backed by a public endpoint that takes a filter and returns matching symbols: POST https://scanner.tradingview.com/america/scan The body is just a filter, the columns you want, a s
